For example, depressing the "NUMBER" key causes the Fig. 12b display to appear, giving a directory or menu of a variety of different types of telephone call destinations. By depressing the "CITY GOV" (city government) key, the display shown in Fig. 12c appears. As illustrated, some of the keys have graphic symbols to designate the call destination, such as the ambulance and fire truck icons. Telephone numbers of the illustrated call destinations have been previously programmed in, enabling the telephone user to merely depress one key for instant "speed dialing". Thus, depressing the "firetruck” key will dial the city fire department.

A three-deep display can provide 4096 different call destinations, all reachable by merely operating one key.

Also, by depressing the "FEATURES" key, the Fig. 12e display will instantaneously appear.
  • Any number of levels of subdirectories are possible, limited only by the memory capacity of the controller.

This eliminates the need to memorize or look up hundreds of telephone numbers. Hand-written personal directories are no longer needed. Once programmed in, these numbers are instantaneously available via keyset manipulation which provides coordinated sets of displays of their call destinations.
